Tracking Network data can be used to prepare for and respond to natural disasters or other public health emergencies.

We Track That

Knowledge of a community’s local infrastructure, vulnerabilities, and resources enables public health professionals to quickly establish priorities and take proper actions during emergency or disaster response. The Tracking Network datasets listed below can be used to

  • identify community-specific threats and hazards, at-risk populations, and community vulnerabilities.
  • make informed decisions about resources needed for public health response or public safety.
  • determine potential public health actions that could lessen or prevent illness, injury, and death.
  • evaluate possible scenarios based on time, place, and conditions.

Types of Data

The Tracking Network presents data in customizable maps, charts, and tables. Map layers can provide important contextual information including overlays of real-time data (weather radar, surface smoke, and active Atlantic cyclones) and points of interest such as day care centers and public schools, fire stations, hospitals, mobile home parks, National Shelter System Facilities, nursing homes, power plants, and urgent care facilities.

It is important to note that the following data are based on total populations, rather than individual members of a particular population.

This indicator includes population estimates (number and percent) of people by race, ethnicity, age, gender, single-parent households, speaking English less than “very well”, and aged 65 years and older and living alone. Data are presented at census tract, county, and/or state level for all states.
